Abstract

This paper proposes a new time-respecting graph (TRG) representation for contact sequence temporal graphs. Our representation is more memory-efficient than previously proposed representations and has run-time advantages over the ordered sequence of edges (OSE) representation, which is faster than other known representations. While our proposed representation clearly outperforms the OSE representation for shallow neighborhood search problems, it is not evident that it does so for different problems. We demonstrate the competitiveness of our TRG representation for the single-source all-destinations fastest, min-hop, shortest, and foremost paths problems.

接触序列时序图的路径算法

本文为接触序列时序图提出了一种新的时间尊重图（TRG）表示法。与之前提出的表示法相比，我们的表示法更节省内存，与有序边序列（OSE）表示法相比，我们的表示法具有运行时间优势，而有序边序列表示法比其他已知表示法更快。虽然我们提出的表示法在浅邻域搜索问题上明显优于 OSE 表示法，但在不同问题上的表现并不明显。我们展示了 TRG 表示法在单源全目的地最快、最小跳、最短和最长路径问题上的竞争力。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
